The libwin32 package on CPAN used to contain a set of Win32-specific modules that provide access to core Windows functionality. Keeping all the modules together in a single distribution turned out to be a big maintenance problem because the releases of the modules were now linked. This resulted in very slow release cycle. The modules are now all available on CPAN separately.

The libwin32 package contains only a single pseudo-module Bundle::libwin32 anymore that will pull in all the module originally contained in libwin32. When you install the Bundle::libwin32, all modules mentioned in "CONTENTS" above will be installed instead.
